Manhole Cover With Grp Sealing Plate Smc Manhole Cover Manhole Cover Making Machine

Product DescriptionProduct Application
FRP/composite material manhole cover with glass fiber and its products (glass cloth, belt, blanket, yarn, etc.) as the reinforced material, synthetic resin as matrix material, mainly composed of unsaturated polyester resin, filler, initiator, thickening agent, low shrinkage additive, film die agent, pigment and reinforced material, etc.
FRP manhole cover is to solve the problem of steel, iron manhole cover is easy to rust and stolen lost, too heavy, brittle crack defects, improve its use function and economic and social benefits and developed a new type of manhole cover.

projectCast iron type of CMCHigh strength composite CMCgrandRecycling value, vulnerable to theftNot stealing, no reuse valueCorrosion resistanceResistance to acid and alkali corrosion resistance is poor, easy to rustResistance to acid and alkali corrosion resistance is strong, does not rustAging resistanceLow degree of resistance to agingHighly resistant to ageing, national level 3 aboveUse cycle5-10 years15-20 yearsThe compressive strengthUltimate load of 36 tUltimate load 50 tThe cost ofThe cost is highLow cost 10-15%Appearance of the colorMonotonous, not colorNovel, coloring, according to industry separation and rubbingssecurityWhole pieces, falling phenomenonIn auxiliary elastic steel frame, no overall risk size, the use of safeUse effectCover, low accuracy of occlusion, are prone to run, jump, ringing phenomenonBuild a bite of high precision, no running, jumping, ring phenomenonEnvironmental protectionHigh energy consumption, more pollutionResource conservation, green environmental protectionThe weight of theHeavy, F700 heavy 110-130 kgF700 heavy 65 kgMain Features1 light dead weight, glass fiber reinforced plastic covers weighs iron covering a quarter, engineering installation and use lightweight flexible opening and closing.
2 good self-locking, glass fiber reinforced plastic circular manhole covers and well unique constraint link structure, prevent the car seat covers jump from well after passing the self-locking function.
3 high strength, the tensile strength of glass fiber reinforced plastic material with Q235 steel and the compressive strength is twice as tall as C30X above, shock, vibration, fatigue and fracture performance is better than that of steel, iron and other materials, used as a bearing structure covers, strength safety conditions than iron manhole covers are more likely to meet.
4 anti-theft, glass fiber reinforced plastic products without recycling value, used as a manhole cover can avoid steel manhole covers are often steal scrap selling hidden trouble, so as to prevent stolen manhole cover loss caused by person, car fall into, or card in the borehole accidents, reduce the economic loss and accident liability of owner.
5 corrosion resistance, natural corrosion resistant glass fiber reinforced plastic materials, used as acid, alkali, salt, water and other corrosive medium environment covers, with technical, economic, competitive advantage.Detailed Images
